Non-solid fuel, which comprise liquid and gaseous fuels, is widely used around the world. Some examples of non-solid fuels are kerosene, ethanol and natural gas. In many countries, a significant percentage of the population has access to non-solid fuels. However, in other countries a very large percentage of people still rely on solid fuels, which include traditional biomass such as charcoal, agricultural residue and wood.

According to the World Bank data, in 2014, some 58.6 percent of the population around the world had access to non-solid fuels. However, the percentage varied when individual regions and continents were taken into consideration. North America, at 100 percent, reported the highest percentage of people with access to non-solid fuels. In countries such as the United States and Canada there is negligible use of solid fuels. Both these nations have reported 100 percent of population having access to non-solid fuels. But in Mexico the figure stood at 84.9 percent.

Europe, too, reported high numbers with many nations being listed in the 100 percent bracket. Montenegro ranked at the bottom among European nations with 61.8 percent people having access to non-solid fuels.

South Asia and Sub-Saharan Africa ranked low reporting just 33.6 percent and 18.1 percent of the people having access to non-solid fuels. Among the South Asian nations, Maldives had largely turned towards the usage of non-solid fuels. Here, 92.4 percent of the people had access to this medium, while in Bhutan the percentage was also relatively high at 62.7 percent.

The lowest figure was reported by Bangladesh, which was just 10.9 percent. In African nations such as Burundi, Rwanda, Guinea-Bissau, Madagascar, Mali, Sierra Leone and Liberia, just two percent of the population had access to non-solid fuels. But, the situation was entirely different in some nations of North Africa such as Libya, Algeria and Egypt, where 100 percent, and Morocco, where 97.1 percent of the population had access to non-solid fuels.
